While genes themselves aren't exactly *composed* of DNA, they are segments of DNA that contain the instructions for building and maintaining an organism.
Here's a breakdown:
* Genes: Units of heredity that determine traits.
* DNA: A long, complex molecule that carries the genetic code.
* Chromosomes: Structures made of DNA and proteins that contain genes.
So, genes are essentially sections of DNA located on chromosomes. These DNA segments contain the code for building proteins, which are essential for virtually every process in the body.
